The first freeze frame of The Dark Knight sets the scene for the film (we are shown an overview of Gotham City Batmans home, this both sets the scene and gives us an overview of what will happen straight away from only one camera view this shows us the thrillers key characters as we know Gotham city is associated with Batman).
This next freeze frame shows the audience other key elements of character to the story men in clown masks committing organized crime (which links the audience to the joker who is a criminal mastermind and dresses like a clown which sets up the story because you know the joker will be a key part performing some kind of crime).
Further backing up scene two is the next scene which shows a man from his back holding a clown mask (this mans identity remains a mystery and as such people are 'drawn in' to watch the film to find out this man we assume is a criminals identity and what he is planning to commit).
In scene 4 we find that these people are in fact committing a bank robbery but as such rises questions why are these people robbing this bank? to fund a plot? to get rich? who has organized them? why have they been ordered to kill each other? it is these questions that cause the audience to question the events of the film and intrigues them to continue watching it.
In the fifth scene we find that these men are skilled tacticians and hackers who are capable of using high tech equipment (the use of props throughout this opening shows that these men are in the power position they have guns, equipment, software etc that can be used to achieve there goals which gives the audience a 'thrill' factor.
In this scene we are shown the extremes of these villains they use another prop (a grenade) to show that they are in the position of power the actions the criminal performs with it is that of removing the primer which in turn causes the man to panic showing that he is the weaker subordinate from the close up of his face and from the camera 'looking up' at the clown criminal.
In this scene we are once again shown that the criminals are more than simple robbers there organized effective people which adds to the mystery how did these skilled men come into criminal motives? who compelled them to commit this bank robbery? (it adds to suspense and mystery of what is happening in the film).
In this scene we are shown the 'opposite' of the criminals we see a well dressed bank clerk (also a skilled man) fighting back against the men showing that although crime is present in the city people are starting to become vigilant an aren't as scared of the criminals of Gotham anymore giving the audience more interpretation of what is going on in the scene.
In the final scene we are shown the front side of this mysterious masked clown in the second scene (we can see this man holds significant importance throughout the story as he has been shown for a second time) once again however the mystery is present who is this man? why is he so filled in on information regarding this robbery and why does he show no fear or worry?
